METALLIC RAILWAY TIE.

Application filed November 10, 1923.

T all whom it may concern:

Be it known that I, NICHOLAS P. Kosrnox, a citizen of the United States, residing at Hayden Lake, in Kootenai County and State of Idaho, have invented certain new and useful Improvements in Metallic Railway Ties, of which the following is a speci fication.

My present invention relates to improvements in metallic railway ties of the channel type, preferably rolled to a concavoconvex form and arched in cross section with the flanges extending downwardly to insure a firm and substantial support in the road bed. The invention also embodies certain improvements in metallic rail seats adapted especially for combination with the metallic tie and arranged in pairs 011 the tie, and supported with saddles, between which saddles and rail seats are interposed resilient supporting members for absorbing shocks from the passing rolling stock. The primary object of the invention is the provision of a cross tie of this character, which although light in weight is strong and du rable and characterized by the presence of resilient means for absorbing the shocks and vibrations due to traffic over the road. Means are also provided for eliminating the danger of spreading rails, and the tie and its accessories by their combination and ar rangement of parts are readily adapted for installation and use and may with facilit and dispatch be laid, tamped and correctly positioned in the road bed.

The invention consists in certain combinations and arrangements of parts as will hereinafter be more fully described and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged in accord with the best mode I have thus far devised for the practical applica tion of the principles of my invention.

Figure 1 is a perspective view showing a tie and its rail seats according to my invent-ion, portions ofthe track rails being shown in proper position.

Figure 2 is a perspective view of the tie and its seats embodying my invention.

Figure 3 is a sectional view transversely of the track rail, showing the rail seat in longitudinal section and showing also a por-- tion of the tie in longitudinal section.

Figure 4 is an end elevation of a tie and its rail seat, showing also the relation of the track rail thereto.

The two track rails are designated A and B, and the tie 1 for supporting the rails is a metallic plate of the proper di mensions which is preferably pressed into a concavo-convex or arched shape in cross section and positioned in the road bed with its side edges or flanges turned downwardly to be embedded in the ballast of the road bed and be tamped therein. Each tie is equipped with a pair of rail seats designated as a whole by the letters C and D, of identical construction, and spaced on the tie to the proper gauge for the two rails.

Each rail seat'comprises a saddle in the form of a plate 2 curved to conform to the upper convex surface of the metal tie upon which it rests with a broad base to insure a firm foundation, and each saddle is provided with end arms 3 and 4 formed integral with the saddle plate 2 and extended transversely of the tie over its edges and under its concave under surface as best seen in Figure 4. These encircling arms provide a flrm and secure clamping means for holding the saddles in proper position and against movement of the saddle in the direction of travel of a passing train, and beneath the tie the arms form transverse ribs that are embedded in the ballast to prevent longitudinal movement of the tie in its road bed.

At its sides each saddle is fashioned with a pair of complementary, vertically disposed plates 5 and 6 each formed as a com pound curve and of sufficient height to permit of a slight elasticity or resiliency when a load is imposed thereon,-but possessing adequate rigidity to receive and support the weight of passing rolling stock. At their upper ends these curved supporting plates are fashioned with horizontal, oppositely ex tending flanges 7 and 8 which form a seat for the flat metallic chair plate 9 which rests thereon. By means of the end upturned flanges 7 and 8 of these respective chair seats which project upwardly at the sides of the chair plates the latter are retained in position against movement parallel with the longitudinal axis of the tie.

The chair plates 9 are fashioned on their upper faces with spaced lugs 10 between which the base of the railis confined, and

between the rail base and chair plate wood shims 11 are interposed to perform the function of cushion blocks and reduce the usual rattling sound due to passage of trains over the ties.

The, rails are fastened in position by means of lugs 12 at each side of the rail, said lugs extending over the base flanges of the rails as best seen in Figure 3, and being perforated for the reception of bolts 13. These bolts it will be seen pass downwardly through the fastening lugs 12, through perforations in the chair plate, and also through the plates forming chair-seats 7 and 8, and the nuts .14 beneath the chair seats? and 8 fasten the boltsin place.

After the saddles have been spaced the proper distance apart on the tie and the latter has been properly tamped into the road bed, the bolts and nuts are applied and tightened, and then the ballast is filled in and tamped over the tie, within and around the saddles of the rail supports, and beneath the chair seats 7 and 8 and the chair plate 9. In this manner the tie and rail supports are firmly anchored in the road bed, and the rail supports form substantial and durable foundations for the rails, absorbing shocks and vibrations of passing rolling stock. The several parts of the tie and its rail supports are readily accessible for 'maintenance of way men and the required repairs tightening of bolts, and other necessary attention may be given in usual manner. The saddle and its clamping arms it will be noted, in addition to supporting the chair seats, reinforce and provide rigidity for the tie tomaintain its arched shape and true longitudinal alinement, and the tie in turn affords a stable foundation for the chair seats.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent isl. The combination with an arched concavo-convex metallic tie, of a. saddle plate thereon having spaced arms encircling said tie, vertically disposed supporting plates above said saddle and horizontally disposed oppositely extending chair plates integral with said supporting plates, a chair seat on said supporting plates and means on the chair plates to prevent lateral movement ot said seat, and means on said seat for fastening a rail thereto.

2. The combination with a metallic tie, of a saddle plate thereon having spaced arms embracing and extending under said tie, vertically disposed supporting plates rising from said saddle plate in the form of compound curves, horizontally disposed, oppositely extending chair plates above the supporting plates and upturned lugs at the ends of said chair plates, a chair seat on said chair plates, and rail fastening means on said chair seat. 7

3. The combination with a metallic tie arched in cross section, of a saddle plate thereon having embracing arms extending under said tie, vertically disposed supporting plates rising from said saddle plate in the form of compound curves, chair plates above said supporting plates having end lugs, a chair seat having rail retaining lugs, and detachable rail fastening means carried by said chair seat.

In testimony whereof I afiix my signature.
